SLC 500 Controller Example Write Single Request Data

In this message example, we use the data table address in

Figure 6.34

to

store the request value (10.0 sec.) that was written to drive parameter 140 -
[Accel Time 1].

In this example, Accel Time 1 is a 16-bit parameter. The most significant
word (MSW) is not used. For PowerFlex 700S drives, Accel Time 1 is a
floating point number. To manipulate REAL data into two 16-bit registers,
see the ‘Communications’ section in Chapter 1 of the PowerFlex 700S AC
Drives Phase II Control Reference Manual, publication PFLEX-RM003.
